Sometimes it's not the exotic location or the money that attracts teachers (me for one), but rather how a person is treated and if they are happy where they are. Add in the impossible demands at times and it is clear why the hotel didn't get any resumes. I do fully agree with you about the Philipas taking the jobs. The standard rate is 30,000 baht a month for most places. I don't know about you or the readers, but I find it hard to live on that amount. I do not drink or go to bars, nor do I have a night life.
I do however, live comfortable with my wife and son and every month it is a struggle to make it until the next payday. I hope that just maybe the schools will realize the pay is too low and do something about it. The Thai teachers in my school make 10,000 a month and live on that, but the way the Thai's live, they can. For a farang to live even similar to the way we did in our home countries, it is very hard.
After going through the work permit, teacher license, and visa fiasco, it seems like the Thai government makes it very difficult for a person to leave their home country and want to come here to work. I know, many say, "you can always go home". That is true and I am sure many do and will continue to as long as the conditions I mentioned aren't addressed.
